as it is, the way we do things is, at least in part, to the advantage and pleasure of the SCs!
For purposes of illustration, let's say we have a holiday travel budget of £5000 for our family next year. I've just pulled that figure out of the air, but let me assure you that any travel money we DO have in this family is already a product of scrimping and saving and cutting back and doing extra work - so there IS a finite amount!)
We could take all the kids on a trip to see my family. And that would be our budget, pretty well gone.
OR. I could plan a trip outside of school holidays when fares are cheaper, for me and DD and, possibly, DH. Then in the holidays we could have a vacation all together, to someplace with the sort of attractions the older kids enjoy and which is age-appropriate. PLUS, we'd have enough left over for the kids to travel to see their mother's family or a trip with DH back to where they grew up and where his family lives, without me and DD.
In our case, the latter preserves more family ties and unity than the former.
If we asked the kids, they'd choose the latter, no question about it. (But I wouldn't ask the kids, because, like Petal says, this is a call they don't get to make.)
